In this paper, a series of ZrO 2 matrix high-temperature self-lubricating composites were prepared by hot-press technique. The effect of Mo and Ag on the friction and wear behavior of the ZrO 2 (Y 2 O 3 )–Ag–CaF 2 –Mo composites in a wide temperature range was investigated. The XRD results showed that CaMoO 4 formed on the worn surface above 400°C. The...
